MOLDING-MACHINE.

Roxbury, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Molding-Machines, of whichthe following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to stiffener molding or shaping machines and is herein illustrated as embodied in a machine for forming heel stiffeners comprising a mold, a support for a stiffener, a die mounted in said support, means for causing said mold and support to aplproach each other, and means for causing t e die to enter the mold.

A feature of the invention consists in means for gripping the margin of a stiffener and means for bending upwardly and molding in that position the forward portions of said margin.

Another feature of the invention consists in i a support for a stiffener, means for clamping the sides of the stiffener against the support and means for bending upwardly and molding in that position the forward portions of said margin.

A further feature of the invention consists in means for snipping the margin of the forward portion of a stiffener to form a tongue, and means for bending upwardly and molding in that position the tongue so formed. 4

These and other features of the invention including certain details of construction and combinations of parts will be described in connection with an illustrative machine and pointed out in the appended claims.

Referring now to the accompanying drawings, Figure 1 is a perspective of a machine in which the present invention is embodied; Fig. 2 is an elevation of the upper portion of the machine; Fig. 3 is a detail section showing the connection between the carrier, the cross-head and the actuating mechanism; Fig. 4 is a perspective showing the support for the counter, and the mold and die which cooperate to form the upturned lip; Fig. 5 is a fragmentary sectional view of the parts illustrated in Fig. 4, a heel stiffener having an inturned Specification of Letters Patent.

margin being shown in place upon the support; Fig. (i is a similar view showing a mold and die in operative relation, portions of the margin of the heel stiffener having been bent upwardly; Fig. 7 is a perspective of a finished stiffener; Figs. 8 and 9 are perspective views of the carrier and the cross-head respectively; Fig. 10 is a perspective of a modified form of mold and die, and Fig. 11 is a perspective of a finished stiffener produced by the action of the mold and die shown in Fig. 10.

Mounted in theframe of the machine are two upright rods 1 which carry at their upper ends between screw-threaded collars 3 and nuts 5 a cross-beam 7, the vertical position of which may be varied by varying the position of the nuts and collars. At the lower central portion of said cross-beam is formed an undercut slot or guideway 9 in which fits a suitably shaped guide 11 carried by a mold 13. This mold (see Fig. 4) comprises two grooves or die cavities 15 which are separated from the sides of the mold by flat gripping faces 17. Arranged to cooperate with the mold is a support 19 and a die 21, said die, in the illustrated embodiment, being "slidably mounted in the support and having a stem 23 which projects below it.- The die is also provided with two upstanding ribs 25, the outer edges of which cooperate with the outer edges of the grooves or cavities 15 of the mold to bend upwardly and mold in that position the forward portions of the inwardly bent margin of the stiffener.

The heel stiffener upon which the illustrative machine is adapted to operate is a partially molded one, its wings or sides having been shaped to conform to thesides of the heel portion of a last and its margin having been turned inwardly. Referring again to Fig. 4 in connection with Figs. 5 and 6, the operation of the present machine will be indicated. The counter having an inwardly turned margin is placed on the support 19 which has the general shape of the heel portion of a last. The support and the mold are then caused to approach each other until the outer part of the inturned margin of the stiffener is gripped between the fiat upper face of the support and the.

flat faces 1.7 of the mold, after which relative movement between the die 31 and the -mold 13 is brought about to bend upwardly the forward portions of the margin 29 to form the lips 31 shown in F 7 and mold them in that position. It will be noted by referring to Fig. 6 that the outer walls of the grooves 15 in the mold lie in the same plane as the outer walls of the socket 33and that the outer faces of the ribs 25 are spaced fromthese planes sufiiciently to permit the lips 31 to be forced upwardly as shown in said figure. It will also be noted that if the intur'ned margin is of sufficient width the upstanding lips 31 will be bent over to an extent at their upper portions and that these bent over portions in the lasted shoe will overlie the top of the ends of the insole lip. In order to carry out the operation which has been briefly indicated above, the support 19 is provided with sockets to receive pins 35 on a carrier 37, said carrier being yieldingly supported upon aspring 39 coiled about a rod 11 which extends into a bore 43 in the carrier, said bore also being arranged to receive the lower portion of the stem 23 'of the die. The rod 41 is adjustably mounted on a cross-head 45 by being threaded through a lug on said cross-head. The screw threads on the lower end of the rod also serve the further purpose of cooperating with a nut 47 to permit adjustment of the tension of the spring 39. The upright arms together with those of the carrier 37 of the cross-head 45 are arranged to slide in guideways in the frame of the machine and are provided with over hanging ends through which are threaded set screws 49 which normally bear upon the upper face of the carrier 37, as shown in Figs. 1 and 2, sothat the cross-head and carrier normally move in unison but that upward movement of the cross-head'with respect to the carrier is permitted, the carrier being normally held be- .tween the spring 39 and the set screws 19.

Plates 51, see Figs. 1 and 2, bolted to the frame form one wall of the ideway in which the cross-head and carrier are slidable. In order to reciprocate the cross-head and with it the carrier an arm 53 on an eccentric strap 55 is pivoted at 57 to dependin lugs 59 on the cross-head 45.

e eccentric 61, which actuates the eccentric strap and arm, is-mounted upon a shaft 63 which is rotated by a driving shaft 65 through-gears 67 and 69; and preferably a one revolution clutch of any convenient type (not shown) is provided in the driving mechanism and is so arranged that the parts will start from and come to rest in the position shown in Figs. 1 and 2., I It is desirable that means be provided for holding the stiffener securely in place upon the support 19 during the operation of the machine, and to this end jaws 71 having faces which are the converse of the corresponding sides of the support 19 are mounted upon levers 73 which are pivoted BEST AVAILABLE cos to the carrier 37 at 75, said levers bei provided at theirlower ends with rolh '77. These rollers are arranged to trai upon cam faces 7 9 formed on the plates and are held in contact with said faces 1 a-coiled spring 81.

\Vith this construction the operation l the machine is as follows :--A stiffener ha ing an inturned margin is placed upon tb support when the parts of the machine a! in the position shown in Figs. 1 and 2, an. power is applied'to the driving shaft 65 12" cause it to make one revolution. The up \vardly moving arm 53 forces-the cross-hem 15 with it; and, during the first part of thmovement, the spring 81 forces the lowel ends of the levers 73 apart thereby'clamping the stiffener securely upon the support. The carrier 37 is also moved upwardly through the supporting spring 39 and continues so to move until the support 19 and mold 13 grip the inturned margin of the stiffener. Further upward movement of the carrieris then prevented, and the continued upward movement-of the cross-head causes the rod 41 to act upon the stem 23 to force the die upwardly into the mold, this position of'the parts being shown in Fig. 6. As the arm 53 moves downwardly the operations described above are reversed, and the parts of the machine come to rest in the position shown in Figs. 1 and'2.

In order to cause the lips 31 to fit closely against the sides of the 11p of the insole it may be desirable to snip. the inturned margin of the stiifener, a finished stiffener sosnipped being shown in Fig. 11, the upstanding lips being indicated at 131. When .this type of stiffener is desired, a die 121 is provided the ribs 125 of which have that faces 83 to provide shearing edges which cooperate with similar shearing edges on blocks 85 which are fastened in the rear portions of the grooves 15 of the mold. The operation of this modification need not be described in detail since it is evident that a mold and die, such as are shown in Fig. 10, may be substituted for the mold and die shown in Figs. 1 and 2. It will be observed, however, that with this form. of die and mold the forward portions of the margin of the stifi'ener are snipped to form tongues and the tongues so formed bent upwardly to produce upstanding lips.

Although the invention has been set forth in connection with a machine adapted to operate upon apartially molded stiffener it should be understood that neither the particular form of the stifiener which is to be operated upon nor the particular construc- BEST AVAlLABLE COP although it should be understood that n the stiffener is incorporated in the bed shoe the lips extend downwardly.
